Barringer (lake sediments) FLUOR (U)
Barringer, lake sediments; fluorometry (uranium)
For the determination of U, a 1 gram sample was reacted with 6 ml of a mixture of 4M HCl and M HNO3 in a test-tube overnight at room temperature. After the overnight digestion the test-tube was immersed in a hot water bath at room temperature and brought up to 90oC and held at this temperature for 1 hour with periodic shaking. The sample solution was then diluted to 20 ml with metal free water and mixed. A 0.1 ml aliquot of the sample solution was used to determine U by a fluorometric method described by Smith and Lynch (1969). A Turner fluorometer was used for the fluorescence measurements in place of the Jarrel-Ash described in the Smith and Lynch paper.
